Questions related to Logistics
Hello, fellow researchers and professionals!
I am a logistics and supply chain management student, eager to deepen my technical knowledge and practical skills in the field. I'm particularly interested in hands-on projects that address real-world challenges, such as optimizing last-mile delivery, improving warehouse efficiency, or leveraging data analysis for better inventory forecasting.
I would greatly appreciate your insights, ideas, or recommendations for project topics that could help me enhance my understanding of logistics and supply chain processes. Suggestions involving tools like Python, Excel, simulation software, or even case studies are highly welcome!
Thank you in advance for your valuable contributions. I look forward to learning from your expertise!
Hello everyone, I worked around 5years in Domestic Purchase and Inter-company Logistics,
My Idea is making Procurement in smarter way with systematic knowledge directly interconnected with computer softwares Globally like a chain to reduce human interaction like physical counts and monitoring the stocks to reorder the Items with the help of IOT interconnecting all departments in serial and dynamic model to provide information to the managers to make just a decision with received info like order qty xxx -> Existing stock xxx -> Automatic lean Material plan comparing with other items -> Exact needed Qty xxxx to order.
( Incoming Job Order ---> Lean Production Plan with,
--->Incoming RM Stocks Counts & Qty in Store or warehouse and also in unused Vendor & Supplier consignment stock,
---> Lean Production ---> Removed Qty Stock after Production and waste
---> Dispatch & Shipping ---> Transits Logistics ---> Coordination with Supplier and Vendors )
I'm not aware if this technology is already in use. This is just a thought draft, can this be done for Master Thesis?
Please share your advice a view over this.
Thanks in Advance!!

Dear Ahmad Fairuz, Liane Okdinawati, and Adirizal Niza
I have read your paper
AHP Application to Select Logistical Location in Upstream Oil and Gas Operation: A Case Study
My comments
1.- In the abstract you refer to three criteria, when in reality you are considering five. However, in my opinion, these are not near enough criteria to use in a project of this magnitude.
For instance, I think that you need to consider also distances, and in risk, many different cases like personal, equipment failure, fatalities, damages by storms, potential blackout because failures of electrical generating equipment on board of platform. What about emergencies and potential evacuations, shortage of spare parts, for pumps and drilling, etc.?
Even when you present a very good collection of valuable opinions from experts regarding criteria, I believe that they are incomplete.
Do you have contingency and remediation plan?
2- In page 1 you say “To reduce the complexity, the Analytical Hierarchy Process (AHP) is used in this study as part of Multi-Criteria Decision Making (MCDM) that can break down the problem into a hierarchy and provide the weight of each element which will result in one best option as a business solution”
You can break a problem to study it in more detail, but not to solve it, because normally, all aspects of the problem are related. For instance, you can have a very ill person on the platform who needs to transported to a hospital, and you need to coordinate many things that link these two issues, the ill guy, the transportation to a hospital and the treatment.
You can plan and study the health problem on a platform and take all the necessary measures, and also analyze independently the general transportation problem, but it is evident that the health problem on the platform may be related with transportation. Consequently, you cannot make a pair-wise comparison between health and transportation criteria and determine which is more important, let alone, in what degree, because health has a component of transportation, and both are complementary. How do you evaluate the mutual contribution?
Because of this, this scenario can be solved by MCDM method, but not using AHP or using the weights its generate.
You agree with this when you say “This will involve the use of specialized transport equipment and material storage in strategic locations, as well as the coordination of complex supply chains involving multiple related stakeholders”.
Therefore, why do you use a MCDM method that does not consider dependency between criteria, but the opposite? It is not an AHP fault, because its structure if for other kind of problems, but it is on the people that use it incorrectly, which, in my opinion, is your case.
Chang et al, that you mention, are by far more realistic that the others experts that are happy with only 4 or 5 criteria
3- In page 3 you say “AHP is one of the MCDM methods found by Thomas Saaty, which is useful for organizing complex problem”
This is incorrect. AHP is unable to deal with complex problems because its hierarchical lineal structure, that is not followed by real-life problems. Today problems have many elements interlinked, in some sort of a network, instead of a lineal vertical relationship.
4- In page 3 “AHP breaks down the problem into a hierarchy, which helps simplify its complexity and displays the connections between various objectives (or criteria) and potential alternatives”
Not really. By breaking a problem, you certainly can better understand it and simplify your comprehension, but the problem is not altered by that. It remains the same.
Just take a car as example; you can break it is engine, body, transmission, etc. to study each separately, but you cannot improve the engine if you do not consider the other parts that are intimately related to it, like power transmission needed to the wheels, type of tires, body weight, body aerodynamics, electrical system, etc. This is a system, and you cannot break it, the same in MCDM problems, they are normally systems, and must be solved as a whole.
5- The AHP method arbitrarily estimates the trade-offs of criteria or objectives, and assumes (Saaty words), that they are equivalent to weights. In addition, since these weights were conceived WITHOUT considering the alternatives, they do not play any role in selecting alternatives. This is not only my opinion but comes from the Shannon Theorem
6- In page 3 “judgment is consistent and does not cause bias in the result”
You forgot to say that if is not consistent, it is forced to be, using a formula.
In addition, even if there is consistency, why is it assumed that what is in the mind of as person is applied to reality?
I hope these comments may help you

How does generative artificial intelligence technology combined with Big Data Analytics and other Industry 4.0 technologies help in planning and improving production logistics management processes in business entities, companies and enterprises?
Production logistics management in a manufacturing company is currently one of the key areas of business management that significantly affects the level of technical and organizational efficiency of business operations. The change in the level of technical and organizational efficiency of business operations also usually has a significant impact and correlates with the issue of business efficiency and affects the financial results generated in the business entity. Among the key segments of logistics in the enterprise are also internal production logistics, on the way of organization of which the efficiency of the operation of production processes and the efficiency of the enterprise also largely depends. In recent years, more and more companies and enterprises have been optimizing production logistics through the implementation of information systems and automation of individual operations in the process. Production logistics is mainly concerned with ensuring the optimal flow of materials and information in the process of producing all types of goods. Production logistics does not deal with the technology of production processes, but only with the organization of the production system together with the storage and transport environment. Production logistics is mainly concerned with the optimization of all operations related to the production process, such as: supplying the plant with raw materials, semi-finished products and components necessary for production; transporting items between successive stages of production; and transferring the finished product to disposal warehouses. Precisely defining optimal production logistics is a lengthy process, requiring analysis and modification of almost every process taking place in a company. One of the key factors in the optimization of production logistics is the reduction of inventory levels and their adjustment to the ongoing production process. This translates directly into a decrease in storage costs. Effective management of production logistics should ensure timely delivery, while maintaining high product quality. Effective production logistics management can be supported by the implementation of new Industry 4.0/5.0 technologies, including Big Data and generative artificial intelligence.
The key issues of opportunities and threats to the development of artificial intelligence technology are described in my article below:
OPPORTUNITIES AND THREATS TO THE DEVELOPMENT OF ARTIFICIAL INTELLIGENCE APPLICATIONS AND THE NEED FOR NORMATIVE REGULATION OF THIS DEVELOPMENT
In view of the above, I address the following question to the esteemed community of scientists and researchers:
How does the technology of generative artificial intelligence, combined with Big Data Analytics and other Industry 4.0 technologies, help to plan and improve production logistics management processes in business entities, companies and enterprises?
How does generative artificial intelligence technology help in planning and improving production logistics processes in an enterprise?

Hegel's Science of Logic involves a trinary process: understanding -> dialectical reasoning -> speculative reasoning -> understanding at a higher level. This is analogous to a period 3 orbit, a return to self mediated by the other A -> B -> C -> A.
A direct consequence of a really strange theorem in dynamical systems due to Sharkovskii is that for any continuous function on the reals f: R -> R, if f has an orbit of minimal period 3 then it has orbits of any minimal period (because 3 is the first number in the Sharkovskii ordering). This happens in particular for certain values of lambda for the logistic map, exhibiting the phenomenon of 'chaos'.
The graph of successive higher iterations of the logistic map exhibit self-similarity, a fractal-like nature. This again mirrors the structure of the logic in which each part is similar in its trinary structure to that of the whole, i.e. Being -> Essence -> Notion, but in Being we have Quantity -> Quality -> Measure. In Concept we have Subjective Notion -> Objective Notion -> Absolute Notion. At a further finer level inside Quantity we have for instance Pure Being -> Nothing -> Becoming, etc.
Hello,my name is Chaimae and my thesis topic is as follow: Management of large distribution logistics in Morocco.
Please tell me what do you think about this subject, wheter it is relevent and original and wether scientific reaserch has sufficiently addressed it. I need youd advices.
This is my thesis topic:Management of logistics in the large distribution sector in Morocco.
And Here is my prob.: To what extent do the operational strategies developed and policies adopted by promoters of large distribution in Morocco allow for competitively managing the logistics chain of large distribution?
And here are the given hypotheses:
• Hypothesis 1: Close collaboration with suppliers could secure supplies, resolve the plethora of supply chains, guarantee merchandise returns, and professionalize logistics personnel.
• Hypothesis 2: Investing in human resources could enhance the distribution chain's supply, storage performance, order preparation, and shipment, fostering staff loyalty and better customer service.
• Hypothesis 3: Inadequate stock positioning in the logistics chain, improper facility localization, and their inflexibility to support a wide range of products and varying volumes might be the cause of the lack of competitiveness among large distribution companies.
• Hypothesis 4: Poor stock management could be the reason behind high logistics costs in large distribution.
• Hypothesis 5: Poor order preparation and shipment conditions might be among the main causes of mismanaging the customer experience.
What do you think? Your comments? Is this a genuine issue? What could I add or remove?"
The results of my logistic analysis research show that the pseudo rsquare is only 0.07. Can I still continue my research?
Hi, I'm doing scientific research about "The impacts of green logistics performance on economic growth: Evidence from China". This is my first time doing research, so my idea gets troubles a lot, I want to ask you guys some questions.
Firstly, about my idea, I am having problems collecting logistics activities data. I don't know whether the data I collect is in a country that has applied green logistics or not because it is only written as "logistic performance index".
Secondly, my instructor wondered why I chose China (in my opinion, because China emits a lot of CO2 so it will be easy to evaluate the impact of applying green logistics on the economy), but she told me that it is not the case, so I have to consider about it again.
It would be great if you could answer ( any websites to collect data..) and give me directions for this idea, I'm a freshman in this field :(. Thank you so much

As we look towards a more sustainable and ethical future, one of the most exciting developments in the world of food is cultivated meat. 🌎🍖
🔬 What is Cultivated Meat? Cultivated meat, also known as lab-grown or cell-based meat, is produced by culturing animal cells in a controlled environment, without the need to raise and slaughter animals. It offers the promise of a more sustainable, humane, and environmentally friendly way to meet our growing global demand for meat.
🌍 Why is it Important?
- Sustainability: Did you know that the meat industry contributes to approximately 15% of global greenhouse gas emissions annually? As meat consumption continues to rise, so does its impact on the environment. Cultivated meat requires significantly fewer resources, such as land and water, and produces up to 90% less greenhouse gas emissions compared to traditional livestock farming.
- Animal Welfare: It eliminates the need for factory farming, where millions of animals endure harsh conditions. By embracing cultivated meat, we can reduce animal suffering on an unprecedented scale.
- Food Security: With the world's population expected to reach 9 billion by 2050, meat consumption is projected to double. Cultivated meat could play a crucial role in ensuring food security while reducing the pressure on our planet's resources.
💲 Price Comparison: Currently, cultivated meat is more expensive to produce than conventionally farmed meat, with prices ranging from approximately $50 to $150 per kilogram. In contrast, the cost of traditional meat production can vary widely but is generally lower.
📈 Future Price Trends: The future of cultivated meat pricing is promising. As technology advances and economies of scale come into play, we can expect the price of cultivated meat to decrease significantly. Projections indicate that it could become cost-competitive with traditional meat within the next decade, making it a viable and sustainable choice for consumers worldwide.
🌟 Engineering Challenges: The development of cultivated meat involves intricate engineering challenges:
- Bioreactor Design: Creating efficient bioreactors for cell culturing and growth is crucial. Engineers are working on scalable designs to optimize cell proliferation.
- Nutrient Formulation: Designing the perfect nutrient solution to support cell growth, mimicking the natural environment, is a complex task.
- Scaffold Materials: Innovations in scaffold materials are vital for replicating the texture of traditional meat.
- Scaling Production: Transitioning from lab-scale production to large-scale manufacturing presents logistical and technical hurdles.
🧪 Scientific Advancements:
- Cell Lines: Scientists are continually improving cell lines to enhance flavor and texture, ensuring cultivated meat is indistinguishable from conventionally farmed meat.
- Culturing Techniques: Developing advanced culturing techniques like 3D bioprinting for complex meat structures is a priority.
- Sustainability Metrics: Research is ongoing to quantify the precise environmental benefits of cultivated meat production.
💡 Let's Collaborate: I believe in the power of innovation to shape a better future. Whether you're a scientist, entrepreneur, or simply curious about the future of food, let's connect and discuss how we can contribute to this exciting journey.
🌱 Let's Keep the Conversation Going: The potential benefits of cultivated meat are vast, from reducing greenhouse gas emissions to safeguarding our planet's ecosystems. Share your thoughts on these environmental impacts and the groundbreaking technology of cultivated meat in the comments below!

Hello,
I am modeling bacterial growth using a logistic growth function:
X' = μX(1-N/κ),
where B' is the increment in bacterial population, μ the specific growth rate, N the total bacterial density, and κ the carrying capacity.
I would like to use the Gompertz model, instead, but I am not sure if I can use the parameters of the logistic model. The parameters for the Gompertz are:
L(t) = AᴮCexp(-e(-B(t-M)))
where:
L(t) is the log of the number of bacteria at time ‘t’ (in hour);
A is the asymptotic log of number of bacteria as ‘t’ decreases indefinitely;
C is the asymptotic amount of growth (log number) that occurs as ‘t’ increases indefinitely;
M is the time (in hour) at which the absolute growth rate is at maximum;
and B is the relative growth at time ‘M’.
What parameters of the logistic can I use in the Gompertz model? Is A = κ, for instance?
Thank you

Dear Colleagues,
Thanks for your prompt responses. But if we plot bifurcation diagram, lypanuov exponent and tragectory plot for function rx(2-3x) it shows different behaviour. So, it attracted my attention to do work on it. The bifurcation diagram of rx(2-3x) suggests that there is no bifurcation but only a little discrete chaos has rate of convergence good as compared with logistic map. If anyone interested in doing work on this new scheme, please send me the email through which we can communicate and whatsapp number also, so that frequency of interaction shall be increased and neck to neck traversing of results can be made jointly.

Hi How to test Heteroskedasticity and autocorrelation in Logistic Panel Regression?
I am trying to identify the three strongest environments in the world for simulation and system dynamics in Operations, logistics and/or Supply chain management - can anyone suggest some environments?
With strong, I mean that have research groups, graduate trainings on the method and UTD-list scientific publications that applies it.
Like what is the impact factor of Cleaner Logistics and Supply Chain Journal ? Its publisher is Elsevier.
I am finding it difficult to operationalize/ define last-mile logistics. As far as I understand there are several last-mile fulfilment options (conventional shopping, locker station etc.).
I believe last mile distribution encompasses last-mile delivery, and last mile fulfilment. How does last-mile logistics differ from these concepts?
The SARS-CoV-2 (Covid-19) coronavirus pandemic has, in some respects, through interrupted chains of international supply and supply logistics, reduced the scale of economic globalisation processes. On the other hand, the need for the development of remote Internet communication has increased due to the introduction of home quarantine periods and lockdowns imposed on selected sectors of the economy in 2020. Consequently, the scale of internetisation and digitalisation of various aspects of business conducted by companies and enterprises has increased. As a result of the growth of the Internet, the importance of information globalisation has increased in terms of remote Internet-based communication. In a multi-year perspective, the importance of environmental and pro-climate globalisation may increase in the future. In view of the above, how else will globalisation processes change in this decade of the 21st century? Will the current energy crisis, the unfolding food crisis, the migration crisis

What do you think are the key factors that could trigger a food crisis in your country in the next quarters and/or years?
Due to many different factors, a food crisis can develop in many countries. The international supply and supply logistics chains that were interrupted during the SARS-CoV-2 (Covid-19) coronavirus pandemic have not been fully rebuilt. Rising fuel prices are driving up the cost of transporting food products to shops. The decline in fertiliser production is also driving up the cost of producing crops. In addition, the war in Ukraine has resulted in a decline in cereal supplies to many countries. The lack of electricity has caused a decline in the production of nitrogenous fertilisers. This then caused a decrease in the production of CO2, which benefits producers of many types of food products. Many food product factories are raising the prices of their products due to increases in raw material, energy and fuel prices. Many production facilities are reducing the scale of production. There may be job cuts. Consumption is falling due to high inflation. If a downturn in the economy occurs in the next quarters, many companies may go out of business and unemployment will rise. In addition, periods of increasingly severe drought, more and more hot days and less and less rain and more and more frequent fires in many parts of the world are causing a significant drop in crop production in agriculture. On the other hand, further food crises may arise in the future in the long term, which will be the result of a global climate crisis developing on a multi-year scale.
In view of the above, I address the following question to the esteemed community of researchers and scientists:
What do you think are the key factors that could trigger a food crisis in your country in the next quarters and/or years?
What should be done to reduce the scale of development of the food crisis?
What is your opinion on the subject?

I have two curves, the first one is a growth curve of a microorganisms reported as cells/mL, whereas the second one is the concentration (as % of the initial concentration) of a specific compound.
I'm trying to understand if there is any correlation between the 2 curves (hence I want to know if the reduction of the compound is depended on the microorganisms growth) but I'm not sure which solution is the best. I tried Pearson correlation but I'm not sure it's the best method since the curves are not linear but they have both a logistic type curve.
I've attached an excel file where I reported an example of the data.
Thanks for your help
Will drones evolve as a parcel delivery model or as objects of intelligent logistics networks meaning that they will deliver to distribution centers not to final users?
